A deformable aerodynamic profiled member has a front profile area and a rear profile area in the outflow area. It is bounded by shells on the pressure side and/or on the suction side, converging in a rear profile edge (6). D33 piezo actuators are provided in at least some locations for deformation of the profiled member. The piezo actuators are aligned such that their length changes essentially in the direction of the planes of the shells when acted upon by electricity.
The invention claimed is: 1. A deformable aerodynamic profiled member comprising: a front profile area; a rear profile area; shells which bound the profiled member on a pressure side and on a suction side, which shells converge in a rear profile edge; and deforming means for varying a curvature of said profiled member by changing length of at least one of said shells in a desired direction; wherein, said deforming means comprises at least one d33 piezo actuator mounted on said at least one shell; and said at least one piezo actuator is arranged on said ...
